Consultant Guide/1977

The Journal of the Air Pollution Control Association presents its eighth directory of air pollution control consultants. This 13-page guide lists individual consultants and firms who have indicated a capability in this field by responding to a questionnaire published in the Journal.

The Consultant Guide is now a computer based program and has a different format than Guides prior to 1976. The basic change is that areas of competence are no longer coded but are shown as categories within five geographical regions. And any certifications granted by the American Academy of Environmental Engineers (AAEE), American Board of Industrial Hygiene (ABIH) and the Board for Certified Consulting Meteorologists (BCCM) are shown adjacent to the phone number in the alphabetical listing.

The Air Pollution Control Association makes no representation regarding the competence of the consultants listed nor does it accept any responsibility for their performance as consultants.

“The Clean Air Act — A Time for Evaluation”

The Third Government Affairs Seminar sponsored by the Air Pollution Control Association was held in Washington, D. C. on April 16-17, 1975. The APCA South Atlantic Section was host for this very successful meeting. The General Chairman of the Seminar Committee was John V. Brink and the Program Chairman was Richard D. Grundy.

The seminar this year was conducted in three sessions. The first session, entitled “The Clean Air Act: State vs Federal Roles,” considered a topic that is receiving increasing emphasis as the national air pollution control program matures. This discussion was chaired by M. Barry Meyer, Chief Counsel and Chief Clerk, Senate Committee on Public Works.

The second session was “Land Use Planning Aspects of the Clean Air Act—Federal, State and Regional Roles.” Mrs. Mary Jane Due, Chairman of the Public Land and Land Use Committee, Natural Resources Section, American Bar Association, served as Moderator of this discussion of indirect source regulations, no significant deterioration, air quality maintenance—concepts that rely heavily on comprehensive land use planning.

“Clean Air Priorities—The Need for Flexibility,” was the title of the third session which was chaired by Austin H. Phelps, Manager Corporate Air Pollution Control, Procter and Gamble Company and President of APCA. The panelists considered the question of how appropriate the standard setting mechanisms of the Clean Air Act are for the resolution of present and future problems.

In this report condensed versions of the prepared statements of the participants are presented. A more extensive summary of the Proceedings, which includes questions and answers, is available from APCA headquarters. The remarks of John R. Quarles, EPA Deputy Administrator, who was the luncheon speaker, were summarized in the June APCA Journal(p. 642).

United States Seen 2.54 Centimeter-ing Its Way to Metric System

On May 3, 1971, the Engineers Joint Council sponsored a panel on metrication at its offices in New York City. Bryce MacDonald of EJC was chairman; he had been instructed to invite representatives of various societies. Its purpose was to “present to the Board of EJC a summation of the situation regarding plans for conversion to the metric system.” The EJC Board will later come to a decision whether it will assume a more active role.

George Arnold of Southern Illinois University, Edwardsville, was named to represent the Air Pollution Control Association on the panel because of his long-standing membership in the Metric Association and his efforts toward exclusive use of international units for pollution measurement.

Twenty-two societies were represented. These included ASME, ASTM, SNAME, ASQC, ASHRAE, ISA, ASEE, ASCE, and ESNE. Among those present was Gregory Schultz of the Material Management Society, who is prominent with the American National Standards Institute and the International Standards Organization. Of the societies present, only six have a firm policy in favor of the metric system. The others are cautiously in favor, or using dual units, or waiting to see what Congress will do about the 1971 Department of Commerce Metric Study Report.

Summary of the 1991 EPRI/EPA/DOE SO2 Control Symposium

The 1991 SO₂ Control Symposium was held December 3-6, 1991, in Washington, D.C. The symposium, jointly sponsored by the Electric Power Research Institute (EPRI), the U.S. Environmental Protection Agency (EPA), and the U.S. Department of Energy (DOE), focused attention on recent improvements in conventional sulfur dioxide (SO₂) control technologies, emerging processes, and strategies for complying with the Clean Air Act Amendments of 1990. Its purpose was to provide a forum for the exchange of technical and regulatory information on SO₂ control technology. Over 800 representatives of 20 countries from government, academia, flue gas desulfurization (FGD) process suppliers, equipment manufacturers, engineering firms, and utilities attended. In all, 50 U.S. utilities and 10 utilities in other countries were represented. In 11 technical sessions, a diverse group of speakers presented 111 technical papers on development, operation, and commercialization of wet and dry FGD, Clean Coal Technologies, and combined sulfur dioxide/nitrogen oxides (SO₂/NO_x processes.

Evaluation of the SO2 and NOX offset ratio method to account for secondary PM2.5 formation

The U.S. Environmental Protection Agency (EPA), state and local agencies have focused their efforts in assessing secondary fine particulate matter (aerodynamic diameter ≤2.5 µm; PM_2.5) formation in prevention of significant deterioration (PSD) air dispersion modeling. The National Association of Clean Air Agencies (NACAA) developed a method to account for secondary PM_2.5 formation by using sulfur dioxide (SO₂) and nitrogen oxides (NO_x) offset ratios. These ratios are used to estimate the secondary formation of sulfate and nitrate PM_2.5. These ratios were first introduced by the EPA for nonattainment areas in the Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM_2.5), 73 FR 28321, to offset emission increases of direct PM_2.5 emissions with reductions of PM_2.5 precursors and vice versa. Some regulatory agencies such as the Minnesota Pollution Control Agency (MPCA) have developed area-specific offset ratios for SO₂ and NO_x based on Comprehensive Air Quality Model with Extensions (CAMx) evaluations for air dispersion modeling analyses. The current study evaluates the effect on American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) predicted concentrations from the use of EPA and MPCA developed ratios. The study assesses the effect of these ratios on an electric generating utility (EGU), taconite mine, food processing plant, and a pulp and paper mill. The inputs used for these four scenarios are based on common stack parameters and emissions based on available data. The effect of background concentrations also evaluates these scenarios by presenting results based on uniform annual PM_2.5 background values. This evaluation study helps assess the viability of the offset ratio method developed by NACAA in estimating primary and secondary PM_2.5 concentrations. An alternative Tier 2 approach to combine modeled and monitored concentrations is also presented.

Implications:

On January 4, 2012, the EPA committed to engage in rulemaking to evaluate updates to the Guideline on Air Quality Models (Appendix W of 40 CFR 51) and, as appropriate, incorporate new analytical techniques or models for secondary PM_2.5. As a result, the National Association of Clean Air Agencies (NACAA) developed a screening method involving offset ratios to account for secondary PM_2.5 formation. The use of this method is promising to evaluate total (direct and indirect) PM_2.5 impacts for permitting purposes. Therefore, the evaluation of this method is important to determine its viability for widespread use.
